Help me!
I want to create a random matrix HM (3,5), it satisfies the following conditions:
1. The value of HM is a nonnegative integer from 0 to 4.
2. The total value of the elements in a row is less than or equal to 5.
Thank you very much!

okay .. an approach would be rejection method .. be careful .. for extremely large matrix this will be a bad idea .. tmp1= randi([0 c],a*100,b); tmp1=tmp1(sum(tmp1,2)<=d); HM=tmp1(1:a,:);

write down all possible ways to get 3 or less than 3 using integers 0-4 like [1 0 0 0 0] [1 1 0 0 0] etc.... pick one of the matrix for each row (randomly) and then use randperm to reorder them.

does b, c and d have any correlation? like in the example case, you have b=c+1, d=c+1
